Very interesting thought hun.. i think there is a loss for every life but not sure whether it always ties back to the family BUT i was VERY close with my great nan, she always pestered me about being married or having kids, i fell PG with DD1, we weren't going to find out the sex but changed our minds, nan was sick and we decided to tell her it was a girl and we were using one of her middle names.. she died not long after and then i am 100% positive she was there for DD's birth.. i have also felt her around DD.. they are connected in some way i am 100% sure of it... and i do believe she had to pass for them to have that connection.
